GASOMETER.

llEC-IFICATION forming part of Letters Patent No. 348,913, dated September 7, 1886.

Application tiled June 13, 1385. Serial No. 168,614. (No model.) Patented in Germany March 31, 1883, No. 24,951, andin Belgium May 1S, IESS, No. 68.901.A

T0 aZZ whom, it may concert/1,:

Be it known that I, Or'ro IN'rZE, a subject of the King of Prussia, residing at Aachen, Prussia, German Empire, have invented certain new and useful Improvements in Gasometers, (for which I have obtained Letters 'Patent in tlie'following countries, dated and numbered as follows: Belgium, May IS, 1885, No. 68,901, Germany, March 31,1883, No. 24,9515) and. I do hereby declare the following` to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, and to letters or [ign res of reference marked thereon, which form a part of this specification.

Referring,` to the drawings, Figures 1v and 2 are vertical axial sections of a gasholder, the tank of which is provided with a bottom embodying my improvements.

In gasholders sheet metal is now preferably employed in place of masonry in the construe` tion ofthe tanks. Up tothe presenttimethese tanks have been constructed with a dat bottom seated ou alevel surface of the ground or upon solid masonry or concrete. This construction, however, renders it very difficult in case of leakage to locate the defective part or to gain access `to the defective part, nor is it possible to protect the bottom against corrosion by protective agents after the holder is placed in position.

This invention has for its object certain improvements in iiuid reservoirs of great capacity-such, for instance, as the water-tanks for gasholders-the said improvements being applicable to all other classes of Huid-reservoirs or storage-tanks.

This invention is designed as an improve nient in the construction of the bottom of the reservoirs or tanks referred to and described in my application for Letters Patent of even date with this, Serial No. 168,613, and it consists in constructing the bottom of the tank or reservoir of a counter-bottom, which may be conical or concave or convex or hemispherical, and a bottom fonpied by re-entering and salient angles, whose apices lie in Vertical planes parallel with the vertical axis of the tank or reservoir, one or more of said salient angles forming` a seat or seats for the support of said tank or reservoir, and in combination therewith ofone or more supports orseat-riugs, substantially as hereinafter fully described.

In the drawings, H indicates thetank of the gasholder, whose bottom B is formed by two reversely-inclined surfaces, b bi', that form a salient angle, b, at the line ofjunction of said bottom B and the counter-bottoni C, and a reentering angle, b, at theline. ofjunction ofthe reverselyinclined surfaces b If, a second salient augle, bi, being formed at the point of junction between the inclined surface b2 and a counter-bottoimG, such salient angle forming a seat, x, from which the tank is supported, either upon a suitable seatring, a, or directly from a loundatioirwall or other suitable support, A, of such height as to afford ready and free access to the entire outer surface of the bottom of the tank H. Y

Instead of supporting the tank from a single seat, it may be supported from a plurality of seats, as shown in Fig. 2. In this construction the bottoni B is supported from seat-rings (t and a. rlhe inner ring` serves as a bearing for the seat x, formed at the line of junction between the counter-bottom C and the reversely-inclined surface lf2-the re entering angie being` formed by said surface b and the inclined surface b', the second salient angle, b, being here formed by said inclined surface b and an inclined surface, bm, that is connected with the reservoir, said second salient angle forming also a seat, m, for the support of the cylinder. In this case there is an outer conical bottom, B, an intermediate angular bottoni, B', and counter-bottom C. It will be observed that the apices of the salient and re-entering angles all lie in vertical planes parallel with the axis of the tank, so that the forces exerted upon the supports for said tank are exerted in a vertical direction, there being no lateral pressures. I am therefore enabled to use supports of considerablyless strength than usual,

. and combine several independent supports, if

desired, and yet afford free access to the entire outer surface of the bottom of the tank.

rlhe counter-bottoni C may have any desired form, provided it be such that the pressures exerted will be in a vertical direction. Thus the bottom may be conical, convex, heini IOO 34ans spherical, or concave'. A further advantage obtained in this construction of bottom is that a very material saving in labor is effected in preparing the ground for the reception of the foundations for both tbc tank and the supports for the bell, as referred to in the application hereinb'efore mentioned.

c is the gas-induction pipe,'and l) the gasbell or inverted cylinder, supported as usual from standards by means of chains provided with counter-weights in the Well-known manner.

Having thus particularly described my said invention, what I claim, and desire to secure by Letters Patent, is-

l. A metallic reservoir i'ori'luids having its iuclosing-wall and bottom connected and constructed to form salient and reentering angles, one or more of said salient angles constituting the seat o1' seats for said 1'eservoir,iu combination with a bearing for said Seat or seats, substantially as and for the purpose specied.

2. A metallic water tank for gas holders having the inclosing-Wall and bottom connected and constructed to form salient and re-entering angles, said salient angles constituting the bearings or seats for the reservoir, in combination with independent foundation Walls or supports upon which the angular bearings of the reservoir are seated, substantially as and for the purpose specified.

3. In iluid-reservoirs,tl1e combination of the inner 4hemispherical or convex botto1n,C, and the outer conical bottom, B,with the intermediate conical bottom, B', as and for the purpose set forth. n Y Y "4L In iiuid-reservoirs,the combination of the hemisplierical or convex counter-bottom O,the conical bottom B, and the intermediate conical or angular bottom, B, with the senti-ings a and a, as and for the purpose specified.

In testimony whereof I aiiix my signature in presence of two witnesses.
